    From the frequently reports problems page:

    20 reports of Erratic Shifting of the Automatic Transmission
    Verified

    The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
